Re-attempted to fit my NovSights (N38 9005 BTW) tonight.
Unfortunately the one that I'd damaged slightly, although it fitted and worked, the fan was making a very loud noise (compared to the other one), so I've had to take them back out
I'd made myself a nice 3d printed tool to insert the collar too. It's a much better way to fit these; Remove the collar from the new LED bulb housing, fit the collar into the socket (using 3d printed tool), then just push the new LED housing into place at the orientation required (leds at 3/9Oclock).
If anyone wants a tool to fit these bulbs let me know and I'll print them one.
